Chesapeake Bay Watershed

The Chesapeake Bay watershed (drainage basin) extends about five hundred miles north from Suffolk, VA (near Norfolk and Virginia Beach) to the headwaters of Otsego Lake, near Cooperstown, NY, and east from mountain streams near Blacksburg, VA to Berlin, MD (near Ocean City). It is essentially a giant, sprawling system of rivers that all drain into one shallow tidal basin, the Chesapeake Bay and its tidal tributaries (average depth, only 21 feet).

Cannon House Office Bldg.

The Cannon House Office Building, completed in 1908, is the oldest congressional office building as well as a significant example of the Beaux Arts style of architecture. It occupies a site south of the Capitol bounded by Independence Avenue, First Street, New Jersey Avenue, and C Street S.E. The building was occupied by the 60th Congress on December 12, 1907. The House, by resolution, directed the Speaker to appoint a select committee of five members to arrange for distribution of rooms.
